Mainframe Modernization & Migration

In an increasingly competitve world, organizations cannot afford to expend their business knowledge and competitive intelligence on legacy applications. Across industries, leaders recognize that transforming these applications is an integral part of maintaining an edge.

Transforming legacy applications can be challenging because of:

Difficulty in extracting business rules

Identifying dependencies on external systems

Lack of system documentation and coding standards

Application complexity due to extensive changes

Enhancements undergone since the initial implementation

SoftSol’s mainframe modernization solution offers a cost-effective and seamless approach for migrating legacy applications to modern architectures so that the migrated applications are maintainable, extensible, and take advantage of latest technologies and platforms.

In this Mainframe Migration approach, the UI layer will be revamped to take advantage of newer technologies while the application itself will remain unchanged in the existing environment. This option provides the least risk to the application because the functionality of the application is not affected.

This approach provides the following benefits:

Revamped user interface

Ease of use

Incorporation of new business rules and edits

Support for newer presentation devices such as PDAs, mobile phones, etc.

The following technologies will reface the existing applications:

Screen-scraping or web-based terminal emulation using NetManage or Attachmate

In this approach, the existing business functionality and knowledge is captured and used to develop a new application that supports the same functionality. Re-engineering is a two step process comprising of reverse engineering of existing application functionality followed by forward engineering to a new platform/architecture.

This approach provides the following benefits:

Discovering and documenting application functionality, which leads to better maintainability through business rules management.

Enhancing business functionality during the re-engineering process.

Removing legacy influences and modifications in the application because it is developed based on documented business requirements rather than migrated from existing code.
